本論文は、ポーランドのクヤフスコ＝ポモージェ県を事例に、再生可能エネルギー（RES）とグリーン水素（GH）の共生による地域のエネルギー転換の可能性を評価。県内のRESポテンシャルは18 TWhで、これから0.38百万トンのGH生産が可能であり、これはポーランドの化石燃料由来水素生産の約30%に相当する。また、岩塩空洞を利用したGH貯蔵の可能性や、経済的障壁についても議論している。
English
This paper evaluates the potential of symbiosis between renewable energy sources (RES) and green hydrogen (GH) at the regional level, using the Kujawsko-Pomorskie Voivodeship in Poland as a case study. The region's RES potential (18 TWh) could produce 0.38 million tons of GH, equivalent to about 30% of Poland's current fossil-based hydrogen production. It also discusses GH storage in salt caverns and economic barriers to hydrogen economy development.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
EUの地域レベルでのグリーン水素戦略の実装可能性を示す事例として参考になる。日本では水素基本戦略や地域水素ハブ構想が進むが、本論文はRES余剰を活用したGH生産と貯蔵の具体的な試算手法を提供しており、日本の地域エネルギー計画への示唆を含む。
In the global GX context
This paper provides a concrete regional case study on green hydrogen production from renewable surpluses, which is relevant to global hydrogen strategies (e.g., EU Hydrogen Strategy, U.S. Hydrogen Hub). It offers transferable insights for regional planning and highlights the importance of storage and cost barriers in scaling hydrogen economies.
👥 読者別の含意
🔬研究者:Researchers in hydrogen economy and regional energy planning can use the methodological framework for assessing RES-to-hydrogen potential and storage feasibility.
🏢実務担当者:Corporate sustainability teams in energy and industrial sectors can reference the cost and infrastructure challenges for green hydrogen deployment.
🏛政策担当者:Regional and national policymakers can consider the strategic value of salt cavern storage and the need for coordinated hydrogen ecosystem development.
📄 Abstract（原文）
Both the energy sector transition processes and the industry transformation processes should in the future be based on the use of green hydrogen (GH) obtained using renewable energy sources (RES). It is the symbiosis of RES and GH that will allow for a sustainable energy transformation of the entire economy. The calculated amount of RES in the Kujawsko-Pomorskie Voivodeship (Poland) is 18 TWh—this would provide 4.2 billion m3 (under normal conditions) (0.38 million tons) of GH. The amount of GH produced from RES surpluses in the voivodeship is about 30% of the current production of GH from fossil fuels in Poland. The calculated GH would power 2.64 million cars. The Kujawsko-Pomorskie Voivodeship has numerous salt caverns where GH can be stored. The most important barrier in the context of GH production remains the effective construction of a hydrogen economy chain, which requires a simultaneous costly transformation of the supply and demand sides. In order to implement GH technology, it is necessary to reduce the costs associated with its production, storage and transmission.
